Description

The camera lens module
Technical field
The present invention relates to a kind of camera lens module, relate in particular to a kind of camera lens module with infrared pick-up and visible image capturing.
Background technology
Along with the development of camera technique, the camera module is widely used in the camera head of various uses, and combining of camera module and various portable electron devices such as mobile phone, video camera, computer etc. obtains numerous consumers' favor especially.And camera lens is the requisite critical elements of camera module, and function that camera lens has directly determines the function of camera.
According to purposes, camera lens has the branch of standard lens, wide-angle lens, special lens etc.Generally speaking, a kind of camera lens only has a kind of function, therefore, adopts the camera of this camera lens generally also only to have a kind of function.If want to make camera to obtain different images, for example, the infrared image of object need become to have the camera lens of infrared pick-up function or the camera that employing has the infrared pick-up function with the lens changing of camera.This measure makes the camera cost of lens changeable raise; In addition, because the different camera lenses of mutually confidential compatibility, and different camera lens often has different structures, thus make that also the structure of camera is complicated more.
Summary of the invention
In view of this, be necessary to provide a kind of camera lens module with infrared pick-up and visible image capturing.
A kind of camera lens module comprises lens barrel, microscope base, filter seat and filter transfer strip.Be provided with optical element in the described lens barrel and lens barrel is contained in the microscope base.Described filter transfer strip is provided with infrared intercepting filter and visible light cutoff filter, described filter seat is positioned on the lens barrel, and described filter transfer strip can slide on the filter seat so that infrared intercepting filter is corresponding with the optical element in the described lens barrel with one of visible light cutoff filter.
Compared with prior art, the filter transfer strip of described camera lens module by can on the filter seat, sliding, make one of infrared intercepting filter or visible light cutoff filter corresponding, thereby the camera that make to use described camera lens module have infrared pick-up and two kinds of functions of visible image capturing not needing to change under the situation of camera lens module with the optical element in the lens barrel.

Fig. 2 is the main body decomposing schematic representation of the camera lens module of Fig. 1.
Fig. 3 is the schematic perspective view of filter transfer strip in the camera lens module of Fig. 1.
Embodiment
Below in conjunction with accompanying drawing the present invention is described in further detail.
See also Fig. 1 and Fig. 2, the embodiment of the invention provides a kind of camera lens module 10 with infrared pick-up and two kinds of functions of visible image capturing.This camera lens module 10 comprises lens barrel 11, lens mount 12, filter seat 13, filter transfer strip 14, infrared intercepting filter 15 and visible light cutoff filter 16.
Lens barrel 11 is contained in the lens mount 12, and can rotate in lens mount 12.Be provided with some optical elements (figure do not show) in the lens barrel 11 so that lens barrel 11 has certain function, as zoom, focus etc.Lens barrel 11 has a toroidal cavity 110 away from lens mount 12 1 ends, groove 110 and lens barrel 11 coaxial cables.
Lens mount 12 is used for holding, carries lens barrel 11, and its inside is provided with image sensor.Lens barrel 11 combines with image sensor in the lens mount 12, can make camera lens module 10 have camera function.
Filter seat 13 is a cylindrical structure, and the one end can be contained in the groove 110 just, and the other end is to the projection 130 that forms two symmetries away from the direction of lens barrel 11, and the free end of projection 130 bends inwards and forms kink 132.Projection 130 inside surfaces middle part is provided with projection 1302.
For filter seat 13 firmly is contained in the groove 110, can adopt bonding way (for example putting the glue mode) that filter seat 13 is bonded in the groove 110.
As shown in Figure 3, filter transfer strip 14 is a rectangular shape, and its width is slightly less than the height that two distance, thickness between the projection 130 are slightly less than projection 130, so that filter transfer strip 14 can move in the zone between projection 130.Kink 132 is used to hold, limit the moving direction of filter transfer strip 14, moves in the zone that it can only projection 130 be surrounded and can not break away from filter seat 13.
Filter transfer strip 14 have two be oppositely arranged and with projection 130 contacted sides 141, first disposal area 142, second disposal area 144, switch and control portion 146 and four grooves 148.
First disposal area 142 is the square of hollow, and it is used for holding infrared intercepting filter 15.At least one angle of first disposal area 142 has first glue place 1422, by at 1422 glue in first glue place infrared intercepting filter 15 being fixed in first disposal area 142.Selectively be that first disposal area 142 also can be rectangle, circle etc.
Second disposal area 144 is the square of hollow, and it is used for holding visible light cutoff filter 16.At least one angle of second disposal area 144 has second glue place 1442, by at 1442 glue in second glue place visible light cutoff filter 16 being fixed in second disposal area 144.Selectively be that second disposal area 144 also can be rectangle, circle etc.
Switching is controlled portion 146 and is extended to form along the end that filter transfer strip 14 has second disposal area 144, and it is provided with three fins 1462.Certainly, fin 1462 also can be one, two or more.Switch when controlling portion 146 it being subjected to displacement when grasping, filter transfer strip 14 just can move between projection 130.Fin 1462 can increase hand and switch the power of controlling between the portion 146 of rubbing.Certainly, the other end that portion 146 also can be arranged on filter transfer strip 14 is controlled in switching.
Two groups of four grooves 148 minutes be positioned at respectively with projection 130 contacted two sides 141 on.Groove 148 lays respectively at the centre position of 144 respective side 141 parts in first disposal area 142 and second disposal area.
Selectively be that filter transfer strip 14 is provided with on 148, one sides 141 of three grooves and is provided with two, is provided with one on another side 141; Two grooves 148 perhaps are set, it is separately positioned on two sides 141, a groove is positioned at the centre position of 142 respective side 141 parts in first disposal area, and another groove 148 is positioned at the centre position of 144 respective side 141 parts in second disposal area.
Stretch in the groove 148 when filter transfer strip 14 moves to projection 1302, can realize the positioning function of filter transfer strip 14,, guarantee the effect of taking so that filter transfer strip 14 can't be moved when taking.
Camera lens module 10 has the filter transfer strip 14 of infrared intercepting filter 15 and visible light cutoff filter 16 by setting, makes one of infrared intercepting filter 15 or visible light cutoff filter 16 corresponding to realize different camera functions with the optical element in the lens barrel 11.When infrared ray cutoff filter 15 moved to lens barrel 11 tops, because infrared intercepting filter 15 allows the light except that infrared ray to enter lens barrel 11, therefore, camera lens module 10 can be made a video recording under general environment or visible light.When visible light cutoff filter 16 moved to lens barrel 11 tops, because visible light cutoff filter 15 allows the light except that visible light to enter lens barrel 11, therefore, camera lens module 10 can be in infrared ray environment or shooting at night.
In addition, those skilled in the art can also do other variation in spirit of the present invention, and certainly, the variation that these are done according to spirit of the present invention all should be included within the present invention's scope required for protection.
